drolyzes gradually, unblocking the amine, which can then react gradually with the epoxy
resin. (3) Polyamine can be reacted with fatty dibasic acid such as dimer acid, to form an
amine-terminated polyamide oligomer (Fig. 3.30), which is nonvolatile, nontoxic, and less
reactive. Epoxy/polyamide ratio is much less critical than the stoichiometric epoxy/
